PIPE-STOCK.

SPECIFICATION forming part of Letters Patent No. 444,686, dated January18, 1891. Application tiled June 28, 1890. Serial No. 357,074, (Nomodel.)

To @ZZ whom t may concern:

Be it known that I, DE VITT C. BEANE, a citizen of the United States,residing at Newark, Essex county, and State of New Jersey, have inventedcertain new and useful Improvements in Pipe-Stocks; and I do herebydeclare the following to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

The object of this invention is to more conveniently and readily adjustand secure a die in position in a pipe-stock, reduce the cost ofconstruction, render the pipe-stock more durable and efficient, and isan improvement on a pipe-threading diestock patented to me November 27,1888, and numbered 393,457.

The invention consists in the improved pipe-stockand arran gementandcombinations of the various parts thereof, substantially as will behereinafter set forth, and finally embodied in the clauses of the claim.

Referring` to the accompanying drawings, in which like letters ofreference indicate corresponding parts in each of the several figures,Figure l is a top plan View of an improved pipe-stock, portions of thecap and handle holders being broken away to more clearly show theconstruction. Fig. 2 is a longitudinal side view, and Figs. 3 and 1 aresectional views showing a securing-pin in a closed and open position,respectively.A

In said drawings, A indicates a bed-plate with handle-sockets at theopposite ends thereof. The center of said bedplate is provided withperforation h to receive the pipe to be threaded, and the upper face ofsaid bed-plate is arranged and adapted to receive a top plate a. Thistop plate is pivoted to the bed-plate A by screws c, passing throughshoulders or projections CZ in the top plate, or may be secured in anyother manner, as desired. Underneath the top plate the bedplate isformed with a recess in the usual manner to receive a die, (shown indotted lines at B in Fig. 1,) adapted and arranged to be in positionover the pipe opening or receptacle A', as seen in Fig. 2. The dieenters the re'a cess in the direction of the arrow shown in Fig. l, andis prevented from passing the de sired or required position by a stop c,preferably made integral with said bed-plate, and stepped or seated inan annular collar or iiange C on the under side of the bed-plate. At theopening in said recess where the die enters there is a circular openingadapted to receive a pin f, shouldered on its under side and formed witha smaller depending piece or extension Z Around this extension Z isfitted a spiral spring m. This spring m is upon the upper portion of theextension Z and is arranged,preferably,to be within the frame A. Uponthe lower or outer portion of the extension Z is adapted a winged heador nut g and closely fitting thereon.

Upon the under side of the bed-plate and surrounding the opening for thesmaller portion Z of the pin f is formed a cam proj`ection 7L, on whichthe ends of the winged head or nut g turn or slide, causing the nut tobind on one side of the projection Z and thereby withdraw the pin fwithin its socket and leave the recess open, free, and clear for therecep tion of the die (shown in Fig. 4) and as will be manifest. As soonas the die has passed into the recess or receptacle arranged for it andthe nut g has been turned backward or loosened, the pin f, under theaction of the spring m, is returned to its normal position, as shown inFig. 3, and thus, in connection with the stop c, holds the die in properposition in the recess in the bed-plate.

In order to strengthen and make more iirm the connection between thehandle portions and the pi pe-receptacle to enable it to resist thestrain, the bed-plate is constructed with braces or shoulders D and D',as shown in Fig. 2.`

In the side of the receptacle A is arranged a thumb-screw K working in athreaded slot in alugorprojection on the bed-plate, as shown in Figs. land 2, for holding the pipe as in a bushing.

Having thus described my I claim as new is-e 1. In a pipe-stock, thecombination, with a cutter-holder and a stock adapted on one side toreceive the cutter-holden of a locking device consisting of a stopin thebed-plate opposite the opening and against which the cut invention, whatter-holder rests, a sliding;V pin opposite saidV adapted'to hold saidpin in its normal position, a Winged nut on said pin, and eamprojectionson the bed-plate, on which said nut is adapted to slide, all said partsbeing ar-- ranged and adapted to operate as described, and for thepurposes set forth.

v In testimony that I claim the foregoing I have hereunto s et my handthis 25th day of June, 1890.

DE WITT C. BEANE.
